Hey all, glad I found this forum. Just took home my first BMW - a 2013 335Is coupe. I've been a Mustang performance guy my entire life so I'm new to the BMW scene. I'm looking at mods that seem fairly basic and just want some opinions. I've been doing a lot of reading and researching and think I'm interested in doing a COBB tune and a FMIC on my car to start. What kind of gains might I see on lets say a COBB stage 2 93 octane tune and the FMIC? I'm also interested in NOT having to cut my bumper cover to fit the FMIC so if anyone can tell me which one I can install without having to cut would be great. At this time I'm not looking to do down pipes. I'm also looking at the BMS one piece intake as well. Any opinions / suggestions about these starting mods from the experts is greatly appreciated.

And please refrain from telling me to use the search function.

Can we tell you there is a performance sub-forum where all your questions might be answered? Someone there might tell you to use the search function, but we are much too polite for that.

Have a little patience with that subforum, it can be slow. Hate to say it but a Search there using Cobb and other performance terms might get you some faster information.
(I'm a Mustang convert myself, was a small block fan since the '66 Pony HiPo I owned for almost 25 years!)

Thanks for your help! I don't go as far back as the 66! I got started on the foxbody cars and have owned several of them. I've also had great experiences with the newer 4.6 motors also and was very close to getting the new BOSS 5.0 but decided on the 335is instead and so far I'm not regretting the decision at all. Now of course the mod bug is back!

Best o'luck! There's much, can be done.

But whatever you decide, DO NOT search on the subjects of:

Methanol Injection

Performance chip integration re: Methanol

Suspension modifications

If you ignore my advice, Winter Depression may set in. You don't want that. No.

First of all, congrats on your new ultimate driving machine. The 335is already comes with more power than the standard 335i models. Adding the Cobb, intake, and fmic will allow you to run the stage 1+ tune which will give you a slight boost in performance gains.
